 Prospects for the measurement of $t\bar{t}\gamma$ with the upgraded ATLAS detector at the High-Luminosity LHC Measurements of $t\bar{t}\gamma$ production are studied in leptonic final states at the HL-LHC, where a data set with an integrated luminosity of 3 ab$^{-1}$ at a center-of-mass energy of 14 TeV is expected to be collected by the upgraded ATLAS detector.

 Prospects for searches for staus, charginos and neutralinos at the high luminosity LHC with the ATLAS Detector The current searches at the LHC have yielded sensitivity to weakly-interacting supersymmetric particles in the hundreds of GeV mass range and the reach at the high-luminosity phase of the LHC is expected to significantly extend beyond the current limits.
